WashingtonCountyGuns Posted May 21 Report Share Posted May 21 (edited) Washington County Machine Guns has received ATF approval for 2 cases (144 rounds) of M433 HEDP 40mm low-velocity rounds. This was an incredibly long journey and just waiting for warehouse to release them for pickup. These will be available at our rental range in the near future. "The M433 High Explosive Dual Purpose (HEDP) round is a 40mm grenade cartridge used primarily in the M203 and M320 grenade launchers mounted on rifles like the M16 or M4. It is designed for both anti-personnel and anti-armor roles. The round contains a Composition B explosive charge and features a shaped charge for penetrating light armor (up to 2 inches of steel) and a fragmenting body that produces approximately 150 fragments within a 5-meter lethal radius upon detonation. It has a maximum range of about 400 meters and is widely used by the U.S. military for its versatility in engaging enemy personnel, light vehicles, and fortifications." Shipper is picking up this week, possibly next week. Here's the shipping Info: QTY 2 x wood crates M433 HEDP (72rds per crate) ==> Box #82 and Box #83; shipping as individual crates (not palletized) --wood crate dims: roughly 24 x 24 x 15 inches --wood crate weight: 53 lbs --total shipment weight: 106 lbs --N.E.W per crate: 7.3 lbs --Total shipment N.E.W: 14.6 lbs --UN 0006 --Haz Class: 1.1E --EX# 2014030871 Edited May 21 by WashingtonCountyGuns 1 1 Quote Link to comment Share on other sites More sharing options...

Haven't set a price yet, but more than $200, but less than $250. They were pretty spendy. Customers will be able to purchase them at our range and shoot them either with one of our 40mm launchers (M79, M203, Stand-Alone launcher) or use their own 40mm launcher. Probably use the 300 yard range once we put up some big targets at 100-yards and 250 yards. Edited May 21 by WashingtonCountyGuns Quote Link to comment Share on other sites More sharing options...
United Surplus Arms Posted May 21 Report Share Posted May 21 that's less than I would have guessed. hope you are able to post video Quote Link to comment Share on other sites More sharing options...
Pyrocoyote Posted May 27 Report Share Posted May 27 How can you own a round that is made for the military? Are there 200. Tax on every round? They are considered high explosive military ordnance. ??? Quote Link to comment Share on other sites More sharing options...

Tax on every round? They are considered high explosive military ordnance. ??? Because we are a FFL 10 / SOT 02 / FEL 20, all 144 of the M433's were transferred under a tax-free Form 3, so the transfer didn't cost us anything. Now IF we sold any under a Form 4, each one would need to be transferred with a $200 tax stamp. There isn't a whole lot I can't purchase with the ATF licenses I hold (details below), so it's not so much "IF" I'm allowed to own something, it's finding a military distributor to sell something to us. Took years and years to get RPG rockets imported from Bulgaria, and few years for these M433's, but the hardest thing we ever had finding a distributor was for the two cases of M213 Grenade Fuzes for the M67 grenade, that took FOREVER, but now it's as simply as filling out a purchase order and they send them to us. Next up on my list is 40mm M583A1 Whitestar Parachute Rounds, found a vendor for new-production ones but damn, they are really spendy, so not sure if I can find a market for them. Holding these licenses means we can legally manufacture, buy, and sell almost anything except for Nuclear, Biological, and Chemical items. Federal Firearm License (FFL) Type 10: Allows manufacturing and dealing in destructive devices (e.g., grenades, large-bore firearms), armor-piercing ammunition, and standard firearms. Requires ATF application, background checks, inspections, and a $3,000 fee every three years. Federal Explosive License (FEL) Type 20: Permits manufacturing and dealing in high explosives (e.g., dynamite, TNT) for commercial use, like mining or demolition. Requires ATF application, background checks, secure storage, and fees ($200 initial, $100 renewal every three years). Special Occupational Taxpayer (SOT) Class 02: Allows manufacturing and dealing in NFA firearms (e.g., machine guns, suppressors, destructive devices with an FFL Type 10). Requires annual $1,000 tax and ATF registration. Edited May 28 by WashingtonCountyGuns 1 Quote Link to comment Share on other sites More sharing options...

Yes, they need to be stored in a High Explosive magazine. We have three magazines: Indoor Low Explosive Magazine (black powder, safety fuse, M81 fuse ignitors, primed 40mm chalk rounds, etc), Indoor High Explosive Magazine (detonators aka blasting caps), and a larger Outdoor High Explosive Magazine (currently has C-4, PETN, RDX, M67, Claymores, Semtex, Shape Charges, HMX, TNT, Dynamite, Blasting Type E, DetCord, KinePak, TexPak, Comp-B, Cast Boosters, M228 Fuzes, M213 Fuzes, ANFO, EDC-4, etc). The M433's will need to be stored in our Outdoor HE Magazine. Edited May 28 by WashingtonCountyGuns Quote Link to comment Share on other sites More sharing options...
M38A1-Josh Posted May 28 Report Share Posted May 28 Congrats on the purchase! I hope you can demo one at the big bore shoot at Southington. When shooting the 40mm HE round at 100 yards, are you worried about frag coming back? Are you going to have the shooter fire then step behind some thick ballistic glass or something to watch the impact? I imagine that if you didn't have a rental/range business and a business purpose for these the vendor selling them probably would refuse to do business with you. I don't think they would sell them to someone for recreation, even if the buyer is properly licensed. Quote Link to comment Share on other sites More sharing options...

The vendor actually offered me some after selling them to WCMG, since they opened that possibility. But I don't have the licensing and facilities for them right now Quote Link to comment Share on other sites More sharing options...

It was about this time 20 years ago that I was nearing the end of my final middle east deployment. I was a gunner so I used to know this stuff but my memory has faded. Yes, there is a minimum safe range for such rounds when fired. As I recall, it was more than 100 meters when fired in training, but in combat it was whatever you wanted. For the MK-19, the fuzes were spin armed and became live about 27 meters from the muzzle. There were some defective fuzes that spontaneously detonated immediately upon arming. I saw a couple of those pop right in front of us but fortunately, no shrapnel came back to us. I shot mostly the stuff from the MK-19, which is a different round, but I think the ammo mentioned above had similar specs. Congratulations for obtaining this ammo. I'm sure someone will have some fun with it. Kevin Bartlett Gunner's Mate, 1st. Class USN/USNR- Retired Quote Link to comment Share on other sites More sharing options...
Pyrocoyote Posted May 29 Report Share Posted May 29 Yes I have type 20 license myself. I thought I was missing something. I have these types hi-x mags also. Wondered how you bought the rounds. Glad you got some. And no they are not worth the 200. Tax to own some. lol. Quote Link to comment Share on other sites More sharing options...

wildbill9ball Posted June 5 Report Share Posted June 5 (edited) When I was in the military I was put on a detail to eliminate 40 mm dual purpose round but i think it was high explosives/ incdnary . We had cases stacked from the ground to the top of my head at each firing position their where 4. I have fired so many of those rounds that it got boring. The round has a 5 meter kill radius and 100 meter danger zone at least that's what I was told. We hit a 1 inch thick by 6 inch frame window mounted to two telephone poles in the ground at 85 yds ( so much for 100 meter danger). We hit it so many times it was bent over about 45 degrees. This was at Fort Benning Ga. I was using a m16 with a 203 grande luncher . Those where the days. Edited June 5 by wildbill9ball Quote Link to comment Share on other sites More sharing options...
